Privacy & Trust
How your data is handled.
Thalassa is built for conversations you can't afford to leak: client calls, advisory sessions, negotiations. The architecture is simple — keep as little as possible, keep it in Europe, and keep your documents on your machine.

What we never keep
No permanent record of your meetings.
Full transcripts
Deleted after the meeting. Our database has no tables for meeting content — enforced by automated tests.
Screenshots
Screen analysis happens for your answer only; captures are not retained.
Your documents' contents
Your knowledge base lives on your device. We hold no copy — we couldn't read your files if we wanted to.
Where it runs
Hosted in Europe.
Answer generation and account infrastructure run in the EU (Frankfurt). We designed for European data-protection expectations from day one: data minimisation, no permanent meeting records, and your knowledge base kept out of our hands entirely.
The overlay, honestly
Private to you — and off your shared screen.
Your answer overlay is private to you and stays off the screen you share — so you stay present and your shared screen stays clean. It floats above your call window, only on your own monitor; move it, resize it, forget it's there.

Your responsibilities
Consent & AI transparency.
You are responsible for obtaining any consent required to transcribe a conversation (in Germany, all participants must consent) and for disclosing AI assistance where required. Thalassa gives you the controls; you decide how to use them.
